These lesson files go along with the video showing how to make realistic fabrics, cotton. I'm charging 5.99 for this as you also get a chair model which you can use in your scenes.
This tutorial aims to teach the basics of creating cotton and I hope it's useful in rendering photorealistic scenes.
The tutorial can be found here:
